Synthesis and Aqueous Aggregation Properties of Amphiphilic Surface-Block Dendrimers
摘要:
[GRAPHICS]A family of dendritic amphiphiles were synthesized from the natural metabolites of glycerol, succinic acid, and myristic acid. The surfaces of these dendrimers display different numbers of alkyl chains and carboxylic acids, varying the hydrophobic-to-hydrophilic ratio over a relatively broad range. In solution these dendritic amphiphiles form supramolecular structures, and these aggregates have been characterized by light microscopy, transmission electron microscopy, and tensiometry. These aggregates can entrap the hydrophobic species pyrene.

The present invention describes a synthetic non-viral vector composition for gene therapy and the use of such compositions for in vitro, ex vivo and/or in vivo transfer of genetic material. The invention proposes a pharmaceutical composition containing 1) a non-cationic amphiphilic molecule or macromolecule and its use for delivery of nucleic acids or 2) a cationic amphiphilic molecule or macromolecule that transforms from a cationic entity to an anionic, neutral, or zwitterionic entity by a chemical, photochemical, or biological reaction and its use for delivery of nucleic acids. Moreover this invention describes the use of these non-viral vector compositions in conjunction with a surface to mediate the delivery of nucleic acids. An additional embodiment is the formation of a hydrogel with these compositions and the use of this hydrogel for the delivery of genetic material. A further embodiment of this invention is the use of a change in ionic strength for the delivery of genetic material.
